Be it known that I, CHARLES E. MILLE', ot' Indianapolis, Marion county, Indiannfhaveivented a naw ,ma

useful Wash-Boiler; and I hereby declarethe following to bea full, clear, and exact description thereof, refer.

'ence being had to the accompanyingv drawings, making part of this speciiication.

This is an improvement in those portablewash-boilerswhich contain provisions for alnoree'ectivo circula.

tion of the boiling water than takes place in the open boiler, 'andconsistsinan varraugeinent of parte, whereby, `firstly, a; constant stream .or streams of boiling water are projectedupon the upper part of the clothes, and are forced through the same bythe combined agencies of hydraulic and-atmospheric pressure, and whereby, secondly, the Vdischargi'ng-nozzles of said streams can be so adjnstedin direction as to strike any desiredpart or portion of the clothes. I

It is well known that fluids in motion have their greatest velocity at the axelsrof theirvconduits, and more particularly so in pots or kettles set upon a stove, and receiving their Vchief heat atj-,the middle of their bottoms.. This tendency is found in practice lso considerable as to seriously'interferelwith the 'effective action of those wash-boilers in whicli au artificial circulation is attempted, by currents ascending ator near the sides of the vessel, and it is to insure such artificial circulation that the iirstor main part of myinveution is chiefiy designed.

VAnother defect in boilers having such artificial circulation, is seen infthe excessive action upon those parte of the clothing` which receive the full impact of the jet or vstream of boilingwater, while otherparts remain in suiciently acted upon, and the second part of my invention is designed, by the provision of adjustable'nozzles, to enable the operator to direct the stream to any or all parts of'the clothes-: without endangering the scalding of her lhands in the attempt to manipulate the clothes themselves'. I( l f Figure 1 is a partially-sectionized side elevation of a washlboiler embodying my invention,

Figure2 is a top view of such a wash-boiler, from which a portion of the bottom proper has been removed.

The body, A, of my boiler is of the usual oblong form, adapted to occupy two openiugsof a customary cook-stove. i v

The bottom proper, B, instead of being iiush with the lower edgesof the body, isA situated slightly higher, so as to remove it from directcontact with the' stove or re.

Attzched to and depending from the bottom, I3, are two drops or pits', C, which are of suchsize andposition .as to enter and occupy the customary'boileopenings of a stort-:,but4 which diiferfrom customary pits fin that they do not communicate directly with the lower part of the boiler-space, other than through a few apertures, b, in the bottom. y v l Y Extendingobliquely across the drop, from the lower and 'inner'angle to the upperand outer angle'tbereof, is a conical or other plate, D, called'by me the directing-plate.v l i' 'i -V Perforations d in this plate are provided, of number er' size suiicientto, perulity ,the descending currentof water to pass below it, but not sufficient t9 interfere with Vthe design and tendencyofsaid plateto forcibly direct the water occupying the pit, and highly heated by direct exposure to the fire, to rise, by its comparative levity, to the open apexd, :1nd,ascending the pipe E, to escapein the form'of jets from thespouts F.

In the. preferred formrof my improvement, as shown, the pipe terminates in two elbows, e e', to each of which a spout is.so tted as to be capable of adjustment in the manner shown by dotted lines in ig.1, so as to enable the operator to direct the streams to any desired part.

The descent of the water in' that part of the pit above the ,directingplate D, together with the' comparative coolness of that part, 'causes a ,partialV vacuum to take placein its upper p'art, which coacts with the pressure of air and water above, to force the latter through the meshes'of the clothes;V

Isam aware that portable wash-boilers have beforebeen'provided with perforated false bottoms, dcilectingplates, and tubes or conduits, through which wateris conducted from the space beneath the false bottom and delivered on top of the-clothes. Such an invention therefore I do not claim.

I claim herein as new, and jot' my inventioni di A portablc-wash-boiler, having'the elevated and perforatedrbottoml, from which depend pits C, having the oblique and perforated directing-plates D, in combnationj'withpipe E and adjustable spout or spouts F;

substantially as set forth.

In testimony of which invention, I hereunto sietdmy hand.l Y i Y l i CHARLES E. MILLER.
